Apple is dropping Intel chips & replacing them with their own CPUs in Macs in 2020 [1], and working on a unified development API where you'll develop one app for iPhone & iPad that will also run on the Mac, so you won't need to write Mac specific apps anymore [2] [3].

It's all rumour & could be wrong. But there's some who feel macOS only has a couple of years left before being discontinued. In that climate, an Electron app is smart because it will be easy to port to iOS / newOS.

I wish them luck, but Microsoft tried this already (Universal Windows Platform).

One thing I fear is that keyboard shortcuts, particular the F-keys, will become a thing of the past.

Apple has in the past been quite good at supporting old software even across hardware chip changes. Sometimes requiring only a recompile, sometimes not even that. Whether the Apple of today is the Apple of old, hard to say.

Seems difficult to make development choices today based on rumors, in any event.

The rumor they just started by saying there are rumors!
